Tucson, Arizona -- Zeta Corporation is pleased to announce that its patented Zeta Rod Systemshave added IAPMO Research &Testing GREEN certification to their IAPMO listing. The products will now bear the UPC™ NSF/ ANSI 61 GREEN stamp, indicating not only that they continue to conform to the standards for Drinking Water Systems Components – Health Effects and the plumbing and electrical requirements set forth in the Uniform Plumbing Code™ IGC 91-2009, but that their use is considered GREEN because it contributes to water conservation, energy reduction and chemical waste reduction in aqueous processes.

The IAPMO GREEN listing for Zeta Rod Systems is qualified in part by independent research data published in 2009 by the U.S. Army Corps of Engineers Contruction Engineering Research Lab. The 18 month Zeta Rod demonstration/evaluation on evaporative cooling equipment on U.S. military bases documented significant overall water savings on cooling tower make-up water of 20%. By replacing standard chemical water treatment techniques, one installation saved approximately one million gallons of water over a twelve month period, contributing to water conservation and chemical reduction requirements for federal facilities by 2016 set forth by Executive Order of the President of the United States.

For industrial cooling and process water treatment applications, the Zeta Rod particle dispersion technology acheives measurable water conservation because cooling systems are able to operate under higher ratios of concentration without forming scale, biofouling or corrosion, and are able to do so without the addition of chemical additives, leaving the waste water available for irrigation or other gray water uses. In potable water applications, the Zeta Rod, which requires no backflush, is used as an alternative to salt-based water softening devices that require water wasting brine regeneration.

IAPMO, the International Association of Plumbing and Mechanical Officials, promotes safe and efficient plumbing and mechanical practices and is the organization that develops and maintains the Uniform Plumbing Code. The NSF Part 61 listing as granted by UPC is recognized by NSF, the National Sanitation Foundation, and ANSI, the American National Standards Institute, who develop the standards for drinking water system additives and components. NSF/ANSI Standard 61 is the American National Standard that ensures pipes, tubes, storage tanks and other products that come in contact with drinking water do not contribute levels of contaminants that could cause serious health problems. Forty-five U.S. states and two Canadian provinces require drinking water system components to comply with NSF/ANSI Standard 61 requirements.

Zeta Rod systems work by creating a capacitor within the piping that prevents deposition of hard water and mineral scale. Additionally, the system performs to eliminate bacteria-harboring bio-films that adhere to pipe and vessel walls, thereby improving water taste, reducing piping and fixture corrosion, and enhancing overall water quality satisfaction.

From July 2007 to September 2008 the US Army Corps of Engineers' Engineer Research and Development Center (ERDC)conducted an independent and thorough comparative study between the Zeta Rod and a conventional chemical water treatment program for cooling towers. Two sites were chosen for the study, Davis Monthan AFB in Tucson, and Fort Huachuca in Sierra Vista, AZ.

The study looked at corrosion, scale and biofouling control as the parameters to be used as the metric to evaluate both programs, however, the ERDC had a special interest in water saving capabilities in order to meet requirements set by Executive Order 13423 regarding water conservation.

This study was also the launching platform for the Zeta Water Management System, which allows remote control, data logging and monitoring of a cooling tower.

The Abstract of the report reads:

The United States Department of Defense (DoD) has a specific legislative mandate to increase its conservation of water and energy. It also is interested in improving the effectiveness of open-loop, cooling water treatment processes at its installations worldwide, for purposes of extending the useful life of evaporative cooling equipment and reducing energy use/costs. A Cooperative Research and Development Agreement (CRADA) was approved to demonstrate that, without using chemical additives, a capacitor-based water treatment system is capable of (1)providing equivalent protection to a chemical treatment program in preventing scale, corrosion, and bio-fouling; (2) allowing cooling systems to be operated in an enhanced water conservation mode; (3) delivering measurable reductions in water usage over conventional methods; and (4)providing control, monitoring, and wireless data transfer via the Internet.

Results documented in the subsequent demonstration and evaluation project showed the technology was able to meet every objective and also was able to deliver a 20% reduction in cooling water use over standard chemical treatment methods.

Application of this technology would allow the DoD to (1) reduce chemical usage, exposure, and disposal expenses; (2) conserve water and energy; (3) facilitate water re-use; and (4) meet new goals for conservation of resources.

We received the following unsolicited email from a residential customer in Scottsdale, AZ:

Dear Zeta,

I wanted to write to you and thank you for your wonderful product! After using it for several months now, I noticed that my pipes were beginning to clear out. I discovered this because the screens in my faucets started collecting debris and had to be cleaned out repeatedly for a short period of time. I’ve also noticed that I’m not getting the hard water buildup in my showers like before. The water here in Scottsdale is extremely hard, and I struggled with it for years. Now, while I still get some white spotting, none of it sticks! I’m able to clean the glass and faucets right off with no trouble at all. Also, it’s nice to be saving the considerable amount of time and money I was spending for the lease and maintenance of my old salt water softener.

I would highly recommend this product for anyone’s home. Thank you Zeta!

Regards,

Heidi Bryant

Scottsdale, AZ

The internet has many web forums in which people ask for opinions on several topics. The Zeta Rod has been questioned in several of these forum. Usually negative opinions are given by "trade experts" who have not used, or tested a Zeta Rod. Their opinions are based on their "previous experiences". However, those who have used the Zeta Rod have positive comments about the technology, such as the following entry that was made in one of those forums:

I think a lot of the criticism of the Zeta Rod system on this forum has been a bit unfair. First, I have no association of any kind with Zeta Rod. I don't sell or install water conditioning equipment. I do have a degree in chemistry.

First, Zeta Rod DOES NOT claim to remove calcium and other dissolved minerals from your water. In fact, they have been very clear that they DO NOT remove anything. Therefore, and chemical test of water that has been conditioned with a Zeta Rod system will have exactly the same chemical composition as the water prior to the test.

If you collect some Zeta Rod conditioned water and let it dry, you will get a deposit -- again, exactly what Zeta Rod states.

What Zeta Rod DOES claim to do is to keep minerals dissolved in the water, so that they do not precipitate on (coat for the non-chemists) pipes, dishes, sinks, etc. (at least prior to the water evaporating). Zeta Rod also claims that any scale present due to evaporation will be easier to remove than normal scale.

I have been using a Zeta Rod system for almost two years and my experience is that both of Zeta Rod's claims are true.

Here are the trade-offs between a Zeta Rod and a traditional water softener; at least as I see them:

1. A Zeta Rod system may have a higher installation cost, but a lower operating cost.

2. In municipalities where traditional water softeners are not allowed, the Zeta Rod is a LOT better than nothing.

3. A traditional water softener will remove metals from your water -- the Zeta Rod will not. However, the Zeta Rod does appear to prevent the metals from depositing on pipes and other surfaces (as long as the water is not allowed to evaporate). During the first few months of use, the Zeta Rod also appears to remove any existing scale that has built up on pipes. Based on my personal experience, the Zeta Rod appears to be MORE effective than a salt based water softener at preventing scale buildup on pipes.

4. While the Zeta Rod does not remove anything from the water, it also does not add anything to the water. A traditional water softener replaces metals (usually calcium and magnesium) with sodium and/or potassium, depending on the kind of salt used with the water softener.

5. A traditional water softener should prevent water spots. A Zeta Rod will not prevent water spots.

6. The Zeta Rod system is MUCH smaller than a salt based water softener.

If I had to install a new system and salt based water softeners were legal in my area, it would be a pretty close call for me. I would probably opt for the Zeta Rod system because of lower operating costs, smaller size and not lower maintenance (don't have to mess with bags of salt).

One of the most frequently asked questions we receive from potential residential Zeta Rod customers is whether the Zeta Rod will help protect their Tankless Water Heater from scaling. The answer is: "Yes, the Zeta Rod will prevent scale deposits from forming on the tankless water heater pipes".

The following is a brief description on how tankless water heaters work and why are they susceptible to scale deposits forming on their pipes.

Tankless water heaters are gaining popularity over the older tank water heater model. Some of the advantages that tankless water heaters offer over the older tank design include: reduced floor space, lower energy consumption and endless hot water available on demand .

Tankless water heaters work by rapidly heating the water in a heat exchanger to the desired temperature as the water flows through the heater. The burner of the unit only turns on when there is demand for hot water, this is how it is able to use less energy while providing endless hot water. Older model hot water heaters store water in a tank and heat it up with a burner (or electric heating elements) when the water drops below a certain temperature. This has the inconvenience that the burner may turn on even when there is no demand for hot water. The following diagram shows a simplified version of a tankless water heater.

Because of the design of the tankless heaters, the water is heated at a very fast rate, forcing the water to come in contact with very hot surfaces on the pipes as it goes through the heat exchanger. This provides conditions that favor minerals in the water to precipitate and form scale deposits on the tube walls. In places with hard water the problem is exacerbated and precautions must be taken to prevent scaling of the heat exchanger tubes.

Mineral scale is primarily composed of calcium carbonate (hardness in the water) which precipitates from the water under certain conditions (such as high temperature, high pH or high concentrations). Scale has a very low heat transfer coefficient, or thermal conductivity. The thermal conductivity of copper is 384 W/(m*K) and the thermal conductivity of scale is 2.6 W/(m*K). This means that scale is about 140 times less efficient in transferring heat than the copper which is used in the tankless heater pipes. The following graph shows the amount of energy increase that would be required to overcome a layer of scale.

The lower thermal conductivity of scale has a direct negative effect on the performance of the tankless water heater. Since the amount of heat transfered to the water is reduced, the unit would have to operate at a higher rate in order to try to get the water to the design temperature, which in turn would result in higher energy consumption. If the scale is thick enough, the unit may not be able to heat the water to the desired temperature at all. And if scaling is very aggressive, water flow can be restricted through the unit and it eventually could lead to tube failure.

The Zeta Rod is an ideal low cost and environmentally friendly option to prevent scale formation in tankless water heaters. A Zeta Rod installed in the main water line entering a home will protect the tankless water heater as well as all the fixtures in the house. The following pictures are courtesy of R&G Sales and show a Zeta Rod displayed with a Noritz Tankless Water Heater at Central Arizona Supply. At this show room's display the Zeta Rod protects the tankless heater and the shower fixtures. This picture shows the small floor space that both the tankless heater and the Zeta Rod take.

Here is their comment on the Zeta Rod installation for the swamp cooler system in the warehouse:

May 19, 2009

Dear Zeta Rod;

I am writing this to let you know what a wonderful solution the Zeta Rod was to our evaporative cooler problem. It has made all of our cooler problems disappear.

Prior to putting the Zeta Rod on the water line that supplies water to our coolers, we had the following problems:

*The air being blown into our warehouse had a damp fishy smell.

*We found that by leaving the coolers on 24/7 the smell was not as bad, but; we used a lot of expensive electricity.

*Running the coolers constantly also wore out the pads, the motors, and the pulleys more often; and they were expensive to replace.

We understand that the Zeta Rod does not allow biofilm to form and that makes our air smell better and helps the coolers run cleaner.

We are also able to turn the coolers off each night.We start them each morning and they run clean and have no smell.Since they only run for 8-10 hours we know we have less wear and tear on the pumps, pulleys and pads!We could not be happier!

Last month R&G Sales, one of Zeta Corporation's Distributors organized a series of Technical an Sales presentations with diverse Plumbing supply companies and Engineering firms in Las Vegas to promote the technology.

The reception and level of interest shown by every company visited was very encouraging, there were many questions asked at the end of each session and many projects were brought up for consideration of the Zeta Rod.

The most pleasant surprise came from one of the project managers at one of the plumbing companies who had installed a Zeta Rod about year and a half ago at a luxury Loft building in Las Vegas. Regarding the performance of the Zeta Rod he had to say the following:

-"We know the Zeta Rod is working because we have had no complains from any of the loft owners who expect to have no problems with hardness issues in the water, and we know for a fact that they would be calling us if they were not satisfied. The building has a water feature in the lobby, usually these water features present a lot of problems, such as scaling of the nozzles, scale build up on the surfaces and bad odors. These problems will have a negative impact on the soothing effect that the feature is meant to have. There have been no nozzles plugging up on this feature, no scale buildup on the surfaces and no bad odors with the water, it remains as clean as it did when it was installed. And the final proof to us was when we had to remove one of the water heaters due to some problems (not related to the water side) and opened it to see the condition of the coils, we found them to be clean of any deposits at all, and after over a year of operation with the water here that is very impressive".

We want to give our thanks to Interstate Plumbing, Hawthorne, and Ferguson's for their time and R&G Sales for the tremendous effort they are doing in growing the market in Las Vegas.

We look forward to the New Year that offers very promising opportunities in the residential, commercial and industrial markets both in the US and Internationally.

Business seems to be off to a good start this new year as the markets in Arizona and Nevada are showing good growth.

One of our residential customers sent us the following testimonial and asked us to post it on this site:

“For the interested parties:

I am writing in regards to the installation and performance of the Zeta-Rod water conditioner. I installed the MFR-30 about a month ago and I can see the difference from my potable water supply with a Zeta-Rod compared to one without. My dishes are coming out much cleaner with little or zero water spots. That is even when I let them completely dry in the dishwasher. Before the Zeta-Rod, I would pull the dishes out and dry them off with a rag to avoid water spots from covering my glasses and plates. One of the other benefits that I have seen is the accumulation of water spots on the shower glass door. It seams to take more showers for the calcium deposits to show on the glass compared to before. An even greater benefit is that I can wipe the spots clean with a little soap and water with a rag instead of using a toothbrush and CLR. It has only been a month, but I am very happy with the performance of the Zeta-Rod. The unit does not take up any floor space, it was easy to install and I never have to worry about maintenance.
